摘要:
平顶山市湛河一桥主桥为双跨独塔单索面矮塔部分斜拉桥,为了分析该桥梁的力学性能,采用大型有限元通用软件ANSYS进行建模,主梁和塔采用空间梁单元(beam188)进行离散,拉索采用只承受拉力的空间杆单元(link10)模拟,建立了该桥梁的有限元计算模型,分别计算了桥梁的内力、自振频率和振型.计算结果表明,对于该矮塔部分斜拉桥,拉索对主梁的轴力和弯矩影响较大,主梁的刚度对桥梁整桥自振频率影响较大,该桥梁低阶振动主要表现为桥梁的整体竖向振动和横向振动.计算结果可为该桥的施工控制及使用阶段的健康检测和维护提供参考
Abstract:
In order to analyze the mechanical properties of the bridge, the large finite element general software ANSYS is used for modeling, the main beam and tower are discretized by space beam unit (beam188), and the cable is simulated by the space rod unit (link10) that only bears the tensile force, and the finite element calculation model of the bridge is established, and the internal force, self-resonance frequency and mode shape of the bridge are calculated respectively. The calculation results show that for the cable-stayed bridge of the low tower part, the cable has a great influence on the axial force and bending moment of the main girder, and the stiffness of the main girder has a great influence on the self-resonance frequency of the whole bridge, and the low-order vibration of the bridge is mainly manifested as the overall vertical vibration and lateral vibration of the bridge. The calculation results can provide a reference for the health inspection and maintenance of the construction control and use phase of the bridge
